Application filed June a, 1917'. Serial No. 173,566.

To all whom it may concern clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a wire holding attachment for the baling chambers of hay presses, and the primary object of the invention is to provide means for securely holding the ends of the tying wires of a bale of hay prior to and during the time that they are being twisted for holding the hay in bale formation.

Another object of this invention is to provide a Wire holder as specified which includes a plate having one end bent at right angles thereto and out out, to which plate is pivotally connected the clamping cam, so that upon pivotal movement of the cam actuating handle, the roughened arouate face of the cam will be moved into a wire gripping position with relation to the under cut-out surface of the right angularly eX- tending projection of the plate.

With the foregoing and other objects in view, this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail, reference will b had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure 1 is a fragmentary side elevation of a hayv press, showing the improved wire clamp attached thereto;

Fig. 2 is an edge elevation of the clamp;

Fig. 3 is a sectionthrough the clamp showing it in a wire engaging position;

Fig. 4: is a detail inverted perspective of the plate side of the clamp; and

Fig. 5 is a fragmentary side elevation showing parts in section, of the clamp when in a wire clamping or engaging position.

Referring more particularly to the drawings, 1 designates th baling chamber of an ordinary hay press, in which the compressed bales are formed and tied, or bound by the usual type of wires which extend about the bale. The clamping structures, generically indicated by the numeral 2 are provided for holding the free ends of the baling or tying wires, while the ends are being twisted to securely bind them about the bale.

The wire clamp structure 2 includes a plate 8 which is attached, by screws or analogous fastening means 4 to vertically extending braces 5 carried by the baling chamber 1. The plate 3 has one end thereof bent outwardly at right angles to the main body of the plate as indicated at 6, and the inner surface of the angled portion 6 is cut out as shown at 7, to form a wire receiving groove in which the wire is securely clamped by a wire clamping cam 8. Thecam 8 has its arcuate surface 9 roughened for firm gripping engagement with a wire as indicated at 10, for clan'iping the wire against the inner cut-out surface of the angled portion 6. The cam 8 is mounted upon the rectangular portion 11 of a bolt 12 which extends through the brace 5, as clearly shown in Fig. 3 of the drawing. The bolt 12 extends eccentrically through the cam .8, so as to move the arcuate edge 9 of the cam toward the inner surface of the angled portion 6, upon rocking movement of the bolt 12 and the cam. The bolt 12 is, rotatably carried by the brace 5 and it has a handle 14lmounted upon the rectangular portion 15 thereof. The handle 1a is bent outwardly as shown at 16, so that the hand grip portion 17 thereof will be spaced from the brace 5 sufficiently to permit the firm gripping of the handle. The handle 14. is positioned upon the opposite side of the brace 5 from the clamp structure, so that it may be conveniently and easily operated.

The wire clamp structures 2 are attached to one side of the baling chamber, and one end of a tying wire is fastened in one of the clamps, after which the wire is passed around the bale and through a second clamp, which alines with the first clamp. The ends of'the wire project beyond the clamps toward each other, so that they may be twisted together, for securely tying them about a bale and holding the hay in bale formation.

What is claimed is 1. A wire clamp attachment for hay balers comprising a plate having one end at right angles thereto, a cam pivotally supported along one face of said plate and hav-.

ing an arcuate roughened edge adapted for coaction with said right angularly extending portion for securely clamping a Wire.

2. Abaling wire clamp attachment for hay presses including a plate, one end of said plate being bent at right angles to the plate, the inner surface of said angularly bent portion being cut-out, a cam roekably mounted along one side of said plate, said cam having an 'arcuate roughened edge adapted for coaction with said angularly extending portion for securely clamping a Wire in the cut-out portion of the inner surface of the angled portion.

3. A baling wire clamp attachment for hay presses including a plate, one end of said plate being bent at right angles to the plate, the inner surface of said angularly bent portion being cut-out, a cam rockably mounted along one side of said plate, said cam having an areuate roughened ed 'e adapted for coaction with said angularl extending portion for securely clamping a wire in the cut-out portion of the inner surface of the angled portion, a bolt pivotally supporting said cam, and a handle mounted upon said bolt for rocking the bolt and cam upon pivotal movement of the handle. In testimony whereof I ai'lix my signature in presence of two witnesses.
